BONFIGLIOLI MOTOR K 63 A 4 K63A4 8D09020032-M046033
The BONFIGLIOLI MOTOR K 63 A 4 K63A4, identified by the codes 8D09020032-M046033 and 12.502.397, is a three phase electric motor built on the frame 63 size with a four pole configuration. It is designed for machine drive duties and is used in industrial applications where a compact motor with reliable rotation is required. The K series is part of the Bonfiglioli motor range used in integrated drive systems. This motor is suitable for pumps, fans, conveyors, and auxiliary industrial equipment.
Product Overview
The frame 63 size is compact and fits machines with limited mounting space. The four pole configuration produces a moderate speed suitable for many general applications. The motor includes a stator, rotor, shaft, bearings, terminal box, and cooling provisions. The housing supports the internal components and provides mounting points for installation. The terminal box provides a safe connection point for the electrical supply and control wiring.
The model codes identify a specific configuration within the Bonfiglioli motor range. Because motor configurations can vary in voltage, frequency, mounting, and options, the nameplate should be consulted for exact ratings. Correct selection requires matching the motor to the load, supply, environment, and control method.
Construction and Design
The motor housing is designed to protect internal components and support the bearing assemblies. The stator windings are insulated to withstand the electrical stresses of industrial operation. The rotor is mounted on a shaft that is supported by bearings selected for the expected radial and axial loads. The shaft extension is machined to accept couplings, pulleys, or other driven components. The fan and fan cover provide cooling airflow over the housing during operation.
The terminal box allows the motor to be connected to the supply and control circuit. Electrical connections should be made according to the connection diagram and local regulations. The mounting arrangement may include feet, flanges, or other interfaces depending on the build. Proper mounting ensures that the motor remains aligned with the driven equipment and that vibration is controlled. Seals and bearing covers help protect the internal components from dust and moisture.
Performance Characteristics
The performance of the K63A4 motor depends on its electrical design and the connected load. Motor speed is primarily determined by the supply frequency and the number of poles. The four pole design provides a moderate speed suitable for many general applications. Torque is produced by the interaction between the stator field and the rotor current. The motor should be operated within its rated voltage, frequency, and duty cycle to maintain stable thermal performance.
Starting current and starting torque should be considered when selecting protective devices and control equipment. The motor should be protected against overload, phase loss, and abnormal supply conditions. Efficiency and thermal behavior are important in continuous operation. Adequate ventilation around the motor helps maintain stable temperatures. When variable speed operation is required, the motor and drive should be selected together to ensure compatibility.
Applications
The Bonfiglioli K63A4 motor is suitable for pumps, fans, conveyors, mixers, packaging equipment, and general machine drives. The frame 63 size makes it useful in equipment where space is limited. The motor can be paired with a gearbox when lower output speed or higher torque is needed.
The operating environment should be considered when applying the motor. Dust, moisture, chemicals, and high ambient temperatures can affect insulation, bearings, and cooling. In such conditions, additional protection or a different motor configuration may be required. The motor should be installed where it can be inspected and maintained. Correct alignment with the driven equipment helps reduce vibration and bearing load.
Installation Guidelines
Installation should begin with a check of the nameplate data and a visual inspection of the motor. The motor should be mounted on a rigid base that can withstand the torque reaction. The shaft should be aligned with the driven equipment to avoid excessive radial and axial loads. Couplings should be fitted according to the manufacturer recommendations and checked for alignment. Mounting bolts should be tightened to the recommended torque.
Electrical connections should be made by qualified personnel following local regulations. The supply voltage and frequency must match the motor rating. The direction of rotation should be verified before connecting the load. Proper grounding is essential for safe operation. After installation, a short run without load helps confirm that the motor operates smoothly and without abnormal noise or vibration.
Maintenance Recommendations
Regular maintenance helps ensure reliable motor operation. The cooling fan and fan cover should be kept clean to maintain airflow. Bearing noise and vibration should be monitored. The motor insulation resistance can be measured periodically to detect deterioration. Electrical connections should be checked for tightness and signs of overheating. Any abnormal noise, smell, or temperature rise should be investigated promptly.
In environments with dust or moisture, additional protection measures may be needed. The motor should be kept clean and dry. Maintenance records help identify trends and support planned servicing. Following a consistent maintenance schedule reduces the risk of unexpected downtime and extends the operating life of the motor.
Selection Considerations
When selecting the K63A4 motor, engineers should confirm the supply voltage, frequency, phase, rated power, speed, frame size, mounting, and enclosure requirements. The motor must provide enough torque for the load under starting and running conditions. The duty cycle and ambient temperature affect thermal capacity. Protective devices should be selected to match the motor and load characteristics.
The motor interface must match the driven equipment or gearbox. Shaft dimensions, flange dimensions, and mounting holes should be checked. For variable speed applications, the motor should be compatible with the selected drive. Correct selection and installation help ensure dependable performance, stable thermal behavior, and long service life.
Conclusion
The BONFIGLIOLI MOTOR K 63 A 4 K63A4 8D09020032-M046033 is a frame 63 three phase motor designed for dependable drive performance in industrial machinery. Its construction supports reliable operation when matched to the correct supply, load, and environment. With proper installation and maintenance, the motor provides stable performance and long service life.
